"Levi's" printed on red tab on 80's selvedge 501s

[Troy Parker]

So I just found this pair of what seem to be 1981-1985 501 redlines but the red tab is different than any I've seen before. It's bigger, thinner, doesn't have the "r", and has "Levi's" printed on to the tab apposed to embroidered. Does anyone know what the deal with this is?

I'm interested in knowing more as well -- bumping this.
